Title: A signalling and controlling device for magnetic tape apparatus
Inventor: CICATELLI RODOLFO
IPC: G11B33/10
Filed: 1969-02-28
Abstract: 1,210,042. Feeding record tapes. AUTOVOX S.p.A. 28 Feb., 1969 [9 Oct., 1968], No. 10841/69. Heading G5R. [Also in Division H2] A commutator (2, Fig. 2) fastened to a disc (3, Fig. 1) driving a take-up reel feeds pulses of a frequency proportional to the speed of rotation of the reel over two brushes (7, 8) to an electronic unit (12, Figs. 3 and 4) which supplies a voltage dependent on this frequency to a multivibrator (13) which is thereby blocked when the reel is rotating at normal speed. When the speed, and hence the voltage, fall below the normal level, the multivibrator (13) oscillates to flash a warning lamp (18), operate a cassette-ejector (14) and cause a motorstabilizer circuit (15) to stop the drive motor (16).
Patent GB-979656-A (GB)
Title: Process for the production of orthohydroxybenzyl alcohols
IPC: C07F5/04
Filed: 1963-03-19
Abstract: The invention comprises tri (ortho-hydroxybenzyl) metaborates of the formula <FORM:0979656/C1/1> in which each of the rings A may be substituted by up to three substituents which are alkyl or alkoxy groups or halogen atoms. The novel compounds may be made by reacting a triphenyl metaborate, in which each phenyl group has at least one unsubstituted position ortho to the borate ester link, with formaldehyde, or a substance which generates formaldehyde under the conditions of the reaction.  The triphenyl metaborates may contain on each phenyl group up to three substituents which are alkyl, or alkoxy groups or halogen atoms.  They may be prepared by reaction of the corresponding phenol with boric acid or boric anhydride, in a proportion of one molecule of the phenol to one molecule of boric acid or a half molecule of boric anhydride.  A water entrainment agent such as benzene, toluene or xylene may be used to distil out water as it is formed. The triphenyl metaborate is generally reacted with formaldehydes or formaldehyde-producing substance at 0 DEG  to 150 DEG C. for from 5 minutes to five hours. Reaction with gaseous formaldehyde may take place at 20-30 DEG C., while with a polymer such as trioxymethylene it is necessary to heat to a temperature high enough to liberate formaldehyde. The reaction is effected in an anhydrous medium.  Ortho-hydroxy-benzyl alcohols are made by decomposing the tri (ortho-hydroxybenzyl) metaborate.  The decomposition may be effected by (i) saponification with an alkali metal hydroxide to give intermediate complexes of the type <FORM:0979656/C1/2> which can be decomposed with a mineral acid or a substance which chelates boric acid more strongly than the ortho-hydroxybenzyl alcohol, e.g., mannitol or sorbitol, and the hydroxybenzyl alcohol is extracted with a solvent; (ii) trans-esterification with an alkanol of 1 to 3 carbon atoms which gives a volatile boric acid ester, which is eliminated by distillation leaving the hydroxybenzyl alcohol; (iii) hydrolysis with a dilute mineral acid and extraction with an appropriate solvent. Examples describe the preparation of saligenol metaborate and saligenol; preparation of p-cresyl metaborate and its reaction with trioxymethylene to yield 2-hydroxy-5-methylbenzyl alcohol; and the conversion of o-cresol to 2-hydroxy-3-methylbenzyl alcohol, o-chlorophenyl to 2-hydroxy-3-chlorobenzyl alcohol and o-ethoxyphenol to 2-hydroxy-3-ethoxybenzoyl alcohol.

Title: Riveting tool
IPC: B21J15/04
Filed: 1930-04-07
Abstract: 348,818. Riveting-tool. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., SIR W. G., WYLIE, H. N., and CRABBE, P. G., Park Side, Coventry. April 7, 1930, No. 10980. [Class 43.] A tool for fixing pierced or tubular rivets is provided with an axiallyslidable sleeve 12 adapted during axial movement in one direction to cause a collet 2 to grip a mandrel 5, adapted for upsetting a rivet, and then to move the collet and mandrel together. The collet 2 is split at 3 to provide spring jaws, and is disposed within a hollow casing 6, which is drilled to receive the mandrel. The sleeve 12 is internally tapered at 13 at its forward end to agree with the taper on the collet. When the sleeve is moved backwards a spring 14 tends to hold the collet stationary, so that the movement of the sleeve causes the collet jaws to grip the mandrel firmly, whereafter further axial movement of the sleeve draws back the mandrel and collet together. To effect release of the mandrel a pin 24 extending through slots 25 in the sleeve 12 engages a part 26 of the collet 2 to limit its forward movement, so that on further forward movement of the sleeve, the collet jaws release the mandrel. A convenient operating mechanism involves the use of lazytongs, compression or elongation of which causes the sleeve to move backwards or forwards as required. The collet may alternatively comprise two jaws hinged together, and may carry ears engaging the slots 25 to prevent rotation. Specification 286,471, [Class 43, Fastenings, Dress], is referred to.
Patent GB-670350-A (GB)
Title: Improvements in or relating to a process of removing salts and other polar substances from solutions
IPC: C13B20/14
Filed: 1949-04-27
Abstract: Salts or organic polar substances (such as complex organic colouring matter in molasses) are removed from a solution by bringing it into contact with a mixture of a basic quaternary ammonium anion-exchange material and a cation-exchange material in its hydrogen form.  The anion-exchange material preferably contains quaternary ammonium groups attached through methylene linkages to aromatic rings of a cross-linked styrene polymer, e.g. a styrene-divinyl benzene copolymer and may be prepared as described in Specifications 654,706 and 670,348.  The cation-exchange material may be a sulphited, sulphonated or sulphated phenol-formaldehyde resin, a carboxylic resin, or a sulphonated carbonaceous material, but is preferably a sulphonated copolymer of styrene and divinyl benzene.  When the anion-exchange material has a density when wet of less than 1-15, e.g. the preferred resin in its chloride form has a density of 1-10, and the cation-exchange material has a density when wet greater than 1-25, e.g. 1.30 to 1-38, the mixture may be gravimetrically separated and the exchange materials regenerated separately.  The seapration may be accomplished in a liquid having a density intermediate those of the materials, e.g. a sugar-solution being treated or another sugar solution. Alternatively water may be passed upwards through a column of the mixed exchange material at a rate, e.g. 4 to 12 1/2 gallons per square foot of column cross-section per minute, to cause a 100 to 300 per cent expansion of the mixture and stratification of the two materials, and the rate may then be increased, e.g. to from 20 to 30 gallons/sq. ft./min., to fluidize the anion-exchange material and thereby separate it from the cation-exchange material. The process may be applied to a sugar solution of from 30 DEG  to 70 DEG  Brix., e.g. a defecated juice, by bringing it into simultaneous contact with the preferred exchange materials the proportions of which are adjusted so that their capacity for adsorbing ions is substiantially equivalent so as to maintain the pH of the juice between 3.5 and 9 during treatment, separating the juice from the materials, and regenerating the materials after gravimetrically separating them.  The separation of the materials may be brought about in a centrifiuge as an alternative to the methods described above.  Specifications 450,574, 474,361, [Group IV], 489,437, 498,251, 521,207, [both in Group IV], 559,941, 577,707 and 670,438, [Group VI], also are referred to.

Corrugating.-A method for making honey. comb or like structures is characterized in that metal foil a is passed between shaped teeth b on a wheel c or f and a first row of shaped peg-like parts d which come into the recesses between the wheel teeth as it rolls upon the metal foil and a second row of peg-like parts e staggered in relationship to the first row d press two layers of already formed corrugated foil, which have previously been treated with a thermosetting adhesive, upon the tops of the wheel teeth band cause said layers to adhere due to the wheel or the pegs being heated. One toothed wheel only is in operation at a time and both are freely mounted on a reciprocable plate which is rotatable about a pivot g to bring either wheel into service. The plate (not shown) also carries a spool i for the foil and foil guides h. The foil is formed to shape by the pegs as the toothed wheel is traversed across the front row. At the end of a traverse the pegs in the back row are transferred to the front row, the other rows move back correspondingly and the other toothed wheel engages the foil and traverses across the pegs in the reverse direction. All four rows of pegs may be heated or only the second row. Alternatively, only the toothed wheels are heated.

Title: Improvements in and relating to signalling systems, especially radio communication
IPC: H03B19/10
Filed: 1922-04-22
Abstract: 205,837. Taggart, J. Scott-. April 22, 1922. Drawings to Specification. Atmospherics and undesired signals, eliminating or limiting; thermionic amplifiers and detectors.-The method of reducing interference by atmospherics and disturbing signals described in Specification 181,400, which consists in multiplying the frequency of received signals, is modified by providing a number of stages of frequency multiplication and by inserting amplifiers before and after any or all of the frequency-multipliers. Loose couplings are arranged between selectively-tuned circuits at each stage. After several stages of multiplication, the signals may be heterodyned to produce low-frequency beats, which may be passed through a telephone or may be amplified, repeatedly multipled in frequency, and again heterodyned to produce an audible note. The frequency multipliers are preferably thermionic valves worked near the saturation point so as to produce harmonics in their output circuits. The whole apparatus, or those circuits tuned to harmonic frequencies, may be screened by metal enclosures to prevent the reception of undesired signals at the harmonic frequencies. The aerial circuit may be slightly mistuned so as to differentiate between desired signals and shock impulses. When spacing and marking waves of different frequency are employed, the frequency multiplication reduces interference by the spacing wave. The method may be applied to the reception of low-frequency signals.

Abstract: 942,487. Toy vehicles. LINES BROS. Ltd. March 29, 1962 [March 29, 1961], No. 11532/61. Heading A6S. In a toy vehicle running on wheels, two wires 3, 4, e.g. of spring steel, are mounted along the sides of the chassis 1 and bear resiliently on the wheel axles 12, the wires being located laterally by side guides 16 and being flexed laterally as they are pushed downwards along the faces of lugs 9, 10, until they are able to straighten out so that they lie vertically beneath downwardly-directed faces of the lugs. The chassis 1 is of die-cast metal and is formed with pairs of slots 5, 6 defined by the guides 16, the inner guides having bearings 11 for the vehicle axles. The slots also have end-pieces 17 to retain the wire springs 13, 14 longitudinally. During assembly, the wire springs are dropped into the slots 5, 6 in the chassis above the axles and when pushed downwardly slide on inclined faces 15 on the lugs 9, 10 as they flex laterally and until they reach the lower ends of the faces 15 when the wires engage underneath the lugs, which may be hook-shaped. The chassis has holes 2, 3 for mounting the body of the vehicle. In a modification (not shown) the lugs have flat downwardly-directed faces and a pillar-like central guide is provided between the lugs presenting an inclined face to the wire springs which when pushed downwards flex laterally against the end slots and the central guide and are finally held in place underneath the lugs by the guide and the end slots.
